a passable digital version of one of my all-time favorite card games that is made worth it by being playable on mobile.

No clue what I was playing since, to my knowledge, there's no tutorial

Good desktop client and great game support, godawful mobile client from what I remember.

Past that, it's fuckin Dominion. Play some Dominion.

It plays like Yugioh! Your turn plays relate to amount of cards in hand and are constrained by a once per turn action (normal summon). But with cards effects you can get to extend your plays almost going through you whole deck.
Learning to keep track of value is also easy as it already keeps tracks of the points of each player. It almost feels like resource racing too.

Functional free port of an already fun card game. Rotating free expansions helps keep it fresh.

A pretty good digital port of a classic game. The base game is absolutely free, and it's good for a few rounds when you're in the mood. Expansions, however, are each separate payments and they're quite expensive to boot. If the DLCs ever go on sale for a reasonable price I'll raise my rating :p
Edit: I forgot that you can't manually pick the cards to be played with. If you feel strongly about certain cards or combos, this could be a deal breaker.

Nope.
